Exosomal PD-L1 Derived From Osteosarcoma is Associated With Pulmonary Metastasis for Patients With Osteosarcoma

2020-07-10

Abstract excerpt

<h4>Background: </h4> Recent studies indicated that exosomal programmed death-ligand 1 (PD-L1) derived from cancers could induce immunosuppression and tumor pathogenesis. However, it is unclear how the exosome influences the osteosarcoma (OS) progression and whether PD-L1 also exists in serum exosomes (Sr-exosomes) of patients with osteosarcoma. Methods We examined serum exosomes from 70 patients with osteosarcom...
